Sonarcloud stopped decorating github PRs

We use sonarcloud on a private project imported from github, and run the sonar scans as part of our pipeline in Azure Devops. Up until 6 months ago, the PR decoration worked fine, but suddenly it stopped. The publication tasks end successfully in the pipeline and the results appear in sonarcloud, but it doesn’t decorate the relevant PRs (even though it seems to identify it and all the properties are as they should be). There are no errors and just one warning that says “Some thymeleaf templates are not indexed”.
The repo is in Java

Hi @alon-vertz-lr , welcome to the community forum!

Could you please post here the task ID of an analysis of a PR where decoration was missing, and one that succeeded?
You can find those ID on the Administration menu of the project, Background tasks, column ID.
